Detailed Description

The present invention will be described in detail with reference to the accompanying drawings and specific embodiments.

The utility model relates to a variable width of cloth height mower of rope drive, as shown in fig. 1, 2, including frame 10, frame 10 is equipped with all around respectively and asks actuating mechanism 13, and every asks actuating mechanism 13 to connect liftable mowing mechanism 12 through rope 6, and four summits in bottom of frame 10 punishment do not are equipped with gyro wheel 11.

As shown in fig. 3, the cable driving mechanism 13 includes a motor 1, a gear a2, a gear B3, a rotating shaft a4, a drum 5, a cable 6, a housing a7, a slider 8, and a housing B9; the driving motor 1 is arranged on a shell A7, the connecting gear A2, the gear B3 and the roller 5 are arranged on a rotating shaft A4, the gear A2 drives the gear B3, the rotating shaft A4 and the roller 5 to rotate, and the rope 6 is lowered along with the rotation.

The rotating shaft A4 is connected with the shell B9, threads are arranged at two ends of the rotating shaft A4, and the sliding block 8 is fixed at the bottom end of the shell A7 and connected with a sliding rail 14 on the shell B9; the rotating shaft A4 can rotate in the shell A7 and can move on the shell B9 at the same time, the shell A7 is driven to move on the sliding rail 14 of the shell B9 integrally, and the rope outlet point of the rope 6 on the roller 5 can be guaranteed to be unchanged.

As shown in fig. 4 and 5, the liftable mowing mechanism 12 comprises a housing 21, a rotating shaft B22, a rotating motor 23, a bevel gear a24, a bevel gear B25 and a blade 29.

The rotating motor 23 is connected with a bevel gear A24, a bevel gear B25 is installed on a rotating shaft B22, the bevel gear A24 drives a bevel gear B25, and the housing 21 wraps the bevel gear A24, the bevel gear B25 and the rotating motor 23.
